An attempt has been made to correlate the mineralogical and bulk chemical characteristics and the textural and structural features of chondritic meteorites. -- The thermodynamic basis for the observed mineral assemblages of the ordinary chondrites is discussed in some detail with respect to the temperature of crystallization, state of oxidation and the liquidus relations. The approximate oxidation fields of the ordinarey, enstatite and carbonaceous chondrites are delineated and compared with a... Topics: Meteorites, Chondrites (Meteorites)
Burrow-casts from fresh-water deposits of the Late Paleozoic have given concrete evidence of the aestivation of the lungfish, Gnathorhiza, and the amphibian, Lysorophus. The structure of these burrows and inference concerning the life habits of their occupants are analyzed, with special attention to Lysorophus. A previously unknown type of burrow, found in association with those of lung fish is described. It is a large, complex structure, ovoid in cross-section and oriented vertically in the...
